Two of Britain's brightest Olympic stars have expressed their disappointment over the postponement of Tokyo 2020 but admitted the authorities have taken an inevitable course of action.

Double taekwondo champion Jade Jones spoke of her "devastation" upon hearing the news, while world record holder Adam Peaty admitted: "This is a matter of life or death and we all need to do the right thing."

Jones told the PA news agency: "I'm truly gutted – you give your heart and soul to something for four years then for it not to go ahead is just horrible.

"Obviously health comes first, and my biggest priority right now is protecting my family and my loved ones, and doing everything I can do to help save the lives of others.

"But as an elite athlete, it is very demotivating and mentally tough.

"I'm a very positive person but the idea, right now, of having to devote myself to another year's slog is a very difficult one."

Jones has been self-isolating along with her best friend and fellow taekwondo world champion star Bianca Walkden in their shared house in Manchester and they have converted their garage into a makeshift training facility.

"We've been making the best of a bad situation," Jones added. "At least this means we can sit back and chill for a little while, and we don't have to train like psychos and do stupid stuff in our house."

Peaty said he would also continue training with a view to making a rescheduled Games an even bigger celebration of the Olympic ideal.

"As an athlete, I am obviously extremely disappointed but this is more important and bigger than me or any of the athletes that would have been taking part," said Peaty.

"Now I know, I can focus on the here and now and, as soon as it is safe to do so, continue with my training and ultimate goal to represent my country at the Olympic Games.

"It will happen and when it does we will all be stronger and able to celebrate what is an extraordinary worldwide event together."

Former Olympic long jump champion Greg Rutherford said a failure to delay the Tokyo Games would have been unfair on athletes who have had their training regimes significantly disrupted.

Rutherford wrote on his Instagram account: "Everyone deserves the right to fight for their place on the podium and with the situation the current crop of athletes were facing, it wouldn't have been fair to host the Olympics this year.

British sports governing bodies welcomed the news, with British Rowing saying the decision would bring "certainty" to competitors.

British Swimming chief executive Jack Buckner said postponement was "undoubtedly the right decision",  a sentiment echoed by GB Cycling performance director Stephen Park.

World Rugby backed the decision to postpone the Games, calling it a "prudent and necessary decision", and adding: "The health and safety of the athletes, fans, and everyone involved is our shared priority and responsibility and we believe the right decision has been taken in these very difficult and unprecedented circumstances."

British sprinter James Ellington agreed as he wrote on Instagram: "In this crazy time for the people of the world, the most important thing is to stay safe, before ANY event.

"Guess my Olympic return will have to wait until next year.

"Gotta roll with the punches, plus it gives me extra time to get my body right. Always try to take the positives out of any situation. Be safe people."
